From 2000 to 2015, CSI ran 337 episodes. Along the way, there were cameos and guest appearances by famous people who, along with the regular cast, created some magical memories. Let’s take a look back at some of the best CSI guest stars throughout the years.

The Biebs played a serial killer whose list of victims ranges from a homeless man to police officers after he bombs a cop’s funeral. His character is pure evil and the CSI initially struggles to pin the crimes to him, but in the episode “Targets of Obsession,” Bieber’s character is eventually tracked down.

Instead of surrendering, he shoots a cop, and is in return killed by a flurry of bullets.

Nick remembers her from a series of cases spanning over the year, and we get to see some, so Swift’s scenes aren’t limited to simply lying there like a lifeless corpse.

Jordan played a role in an episode about the deaths of three unidentified teens that sends the CSI team into the world of rap music. The episode also has appearances by Method Man, Travis Barker, Obie Trice, and Akon.

Seyfried appeared on an episode about a criminal defense lawyer who gets murdered at her son’s wedding, and is discovered to have not been very kind to the bride, the groom’s father, and seemingly everyone else. Her character, Lacey Finn, speaks with the CSI team.
